. SPECIFICATION forming part of Leiters Patent NO. 293,619, dated-February 19., 1884.

Application filed November 27, 1883. (No'mollel.)

[[ all whom it may concern;

Be it known that I, RICHARD T. BISHOP, a citizen of the United States, residing at-St.' Louis, in the county of St. lLouis and State of Missouri, have invented a newand useful Wheel, ofwhich the following is a specification, reference being had to the accompanying drawings. I

This invention relates towheels for vehicles, machinery, and other purposes; and it has for its objects, iirst, to` reduce the friction to a minimum, thus insuring the easy running of the wheel; secondly, to provide improved means whereby the wheel may be easily tightened upon its bearings when the latter become worn; thirdly, to devise an improved construction, whereby the wheel shall be absolutely prevented from becoming loose upon or coming off the shaft or axle while in operation 5 and, fourthly, in an improved construction of the spindle, and the method of attaching the same to the shaft or axle, all as will be hereinafter fully described.

In the drawings hereto annexed, Figure 1 is a longitudinal sectional view of the end of an axle or shaft equipped with my improved wheel and spindle. Fig. 2 is a transverse sectional view on the line m x in Fig. l, and Fig. 3 is a detail view of the spindle detached.

The same letters refer to the Same parts in all the figures,

A in the drawings designatesthe shaft or axle, the end of which is cut off diagonally,

or beveled on its under side, as shown at B, and provided with a recess, C, the lower or inner side of which forms an outwardly-projecting lug or tongue, D. The upper edge of `the outer end of the axle is provided with an overhanging iiange, E, which, when the improvement is applied to vehicle-wheels, forms a sand-guard.

F designates the spindle, the outer end of which is tapering or conical, as shown, being largest at its outer end. vThe inner'end of the spindle has an arm, G, the upper side of which is beveled, so as to t against the end of the` axle, and provided with a projecting portion, H, tting in the recess C, the lug or tongue D of which forms a firm support for the inner- 5o most portion of the spindle-arm G. The spindle is secured to the end'of theaxle by means of clips or bands l, encircling the said Spin`dlearm and the end of the axle. a

J designates the wheel, the hub of which comprises the Sheath or casing K and the cap L. The sheathl consists, mainly, of a cylindrical sleeve, having at its inner end an inward-extending angular flange, M, provided about .midway of its length with a bulging portion, N, forming an interior annular groove, 6o O, and having near its outer end an exterior angular flange, l), against which rest the inner sides of the spokes Q,'which are dovetailed at their inner ends. The outer end of the sleeve or sheath is interiorlyscrew-threaded, as at R, to receive the threaded flange S, projecting inward from the cap L, which latter 'may thus be tightened up against the spokes, so as to hold the latter in position. The angular ilange S is interiorly screw- 7o threaded, so as to receive a plug, T, terminating'at'its inner end in a conical point, U, and having at itsouter end a polygonal opening or recess, V, to receive a suitably-constructed wrench or tool, by means' of which 75 it may be tightened when required.

Between the inner end of the sleeve or sheath of the hub and the cylindrical portion ofthe spindle are interposed a series of cylindrical anti-friction rollers, W, having pointed 8o or conical ends X.

Placed in the interior' groove, O, of the hub are a series of anti-friction balls, Y Y, bearing against the outer conical end of the spindle. The latter is provided at its outer endv with a 8 5 recess, Z, in which are placed anti-friction balls A2, bearing against the conical end U of the plug T. I

From the foregoing description, taken in connection with the drawings hereto annexed, 9o the operation and advantages of this invention will be readily understood. The wheel is adjusted upon the spindle before the latter is attached to the axle, and the spindle being larger Aat its outer than at its inncrend, will absolutely preventthe wheel from coming off. The attachment of the spindle to the axle is simple and easily effected, but is rigid and secure. The bearing of the wheel against the V three set-s of rollers insures the easiest motion Ioo 2 p 293,6io

with the least possible friction. Any slack caused by wear maybe instantly compensated for by simply tightening the plug T, whereby the Wheel will be drawn in an outward direetion upon the spindle, and the rollers W' and Y tightened up against the outer conical portion of the latter, While the conical bearing U of the plug T will be tightened against the friction-balls A. The sheath or casing of t-he hub also forms a capacious receptacle, which may be filled with oil, thus rendering the wheel self-lubricating.

I claim as myinvention and desire to secure by Letters Patent of the United Statesl. The combination, with a shaft or axle beveled on its under side at its outer end, and having a recess provided at its inner or loiver edge with an outwardlycxtending lug, of a detachable spindle having a projecting portion adapted to iit in the said recess, and suitable connecting clips or bands, substantially as set forth.

2. The combination of an axle having beveled outer end, B, and overhanging flange E, with a detachable spindle having a tapering or conieally-enlarged outer end, and inwardlyextending beveled arm G, and a wheel mounted upon the said spindle, substantially as set forth.

3. The combination, with a spindle having a tapering or conically-enlarged outer end, ot' a Wheel consisting ot' a mainly cylindrical sheath or casing having a bulging portion forming an interior annular groove, an inwardprojccting flange at its inner end, and 55 an exterior angular llangc near its outer end, and a cap having an inwardly projecting threaded flange itting in the outer end of the sheath, and interposed frictioirrollers, substantially as set forth. 4 0

4. The combination of aspindle having a tapering or conically-cnlarged outer end provided With a recess, Z, with awhcel comprising a sheath, K, having ilanges M l), and interior annular groove O, cap L, having ilange 45 S, provided with exterior and interior screwthreads, and plug T, having conical inner end, U, and recess V, and the friction-rollers V, and balls Y and A2, all arranged and operating substantially as set forth. 5o
